Predictably my recently purchased 1995 e320 has thrown a minor wobbly It gets quite warm, I.e around 100 on the gauge when driving fairly normally, I would have thought it should stay closer to the just above 80 that my others do. When hot it will misfire on one or two cylinders and as...

Hello all, I have a 1998 V6 SL320, which suddenly drops to firing on what feels like three cylinders only. Cutting the engine off, then restarting immediately, always cures the problem. The problem usually, but not always, occurs after a run of 200 km or more, but after the first occurrence...

Cylinder misfire on M120 engine (SL70) Hi all, There was some misfiring detected in 2 or 3 of the cylinders in my car. According to the dealer, it would require about 32 manhours to remove cylinder heads to check (so some £5,000). Other option is to run some miles on it to see if...

Hi all, really hoping that someone can help. My C230 threw a P2006 (Intake Manifold Runner Control Stuck Closed Bank 1) error code and after removing the Intake Manifold I discovered the whole unit needed replacing, so sadly the cheap fix went out the window. I also found that the MAP Sensor...

Hi everyone, new to the forum and already looking for help lol:fail Just availed myself of a '97 V230 Ambiente having had to pension off my 113 Vito conversion. My most immediate area for attention is the ignition system. At low revs everything is smooth but under any load or increased...

Hi My wife's A150 has a very small misfire, or more like an intermittent judder (very small) when the engine is warmed up. You can only really feel it when sat in traffic or when cruising at a constant speed. The rev counter doesn't even dip when it occurs but it is just noticeable. We still...

When cold and trying to accelerate anything more than very gently it misfires between 2-3,000 rpm. Not always from completely cold, even a restart after a few hours. Been to my indie for a service and no error codes were logged, also no failure indications during the misfiring. Once warm it...

I have a regular misfire on my '94 SL 500. I've changed the plugs,distributor caps and rotor arms, but it has made no difference. Seven plugs are the right light brown colour; the front left plug is just oily - not carbon fouled - with no sign of combustion in that pot. I'm thinking a new...

If I try revving the engine whilst standing still it will not rev above 2300 -2500 rpm without trying to cut out, when I'm driving there's not a single problem with it, idling is smooth and when on the road I can floor it and doesn't miss a beat no loss of power, any ideas anyone?
